Other drugs may interact with pitcher plant, including prescription and over-the-counter medicines, vitamins, and herbal products. Based on these available therapies, developing novel treatments against HSV-1 infection would be highly beneficial. But since the risk is so low for populations at large, it is hard to justify vaccinating everyone, particularly because the vaccine can have serious side effects. Perng, G. & Jones, G.
